[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] This utility model provides a technical solution, such as Figures 1-6 As shown; a rotary grinder for electromechanical repair includes a base 1, which is installed on the ground, and a sliding groove 11, which is opened at the center of the upper surface of the base 1, and a fixing screw 111 is installed above the center of the groove.

[0043] In this embodiment of the utility model, the sliding groove 11 can be used to conveniently position the grinding mechanism 3 during movement, and the fixed screw 11 can be used to enable the movable grinding mechanism 3 to move slowly on the base 1, thereby enabling it to efficiently grind the rotating shaft and improve work efficiency.

[0044] The clamping and fixing mechanism 2 is located at one end above the base 1 and includes: a square clamping frame 21, located at one end above the base 1 and connected to the base 1 via support legs 211, with clamping claws 212 on both sides of the center of the frame, the two clamping claws 212 being symmetrically distributed, the upper and lower ends of the clamping claws 212 being slidably connected to the square clamping frame 21, and clamping pads 213 being provided on the clamping teeth of the clamping claws 212; an adjusting screw 22, movably mounted on one end of the clamping claws 212 and threadedly connected to the square clamping frame 21, with an adjusting handle 221 mounted on one end of one of the adjusting screws 22; and a linkage shaft 23, mounted on the upper ends of the two support legs 211, with its two ends connected to the two adjusting screws 22 via sprockets and chains, respectively.

[0045] In this embodiment of the utility model, by using the arrangement of two symmetrical clamping claws 212 and the linkage of the linkage shaft 23, the two adjusting screws 22 can rotate simultaneously, thereby enabling the clamping claws 212 to move simultaneously toward the center of the square clamping frame 21, so as to quickly clamp the rotating shaft and ensure that the center of the rotating shaft is aligned with the grinding round hole 321.

[0046] In this embodiment of the utility model, the two adjusting screws 22 rotate in opposite directions and are respectively threaded to the square clamping frame 21, thereby ensuring that the two clamping claws 212 can move closer to or further away from the rotating shaft synchronously, which is convenient for operators.

[0047] In this improved embodiment, the upper and lower ends of the clamping claw 212 are slidably connected to the square clamping frame 21, which can limit the clamping claw 212, prevent it from deflecting, and ensure the smoothness of its adjustment. At the same time, the setting of the clamping pad 213 can avoid direct contact between the rotating shaft and the clamping claw 212, and prevent the rotating shaft from being damaged and scratched during clamping.

[0048] A mobile grinding mechanism 3 is mounted above the base 1 and includes: a grinding seat 31, mounted above the base 1, with support pulleys 311 at the four corners of its lower surface, the support pulleys 311 slidingly contacting the base 1, an internal threaded adjusting cylinder 312 at one end of the center of its lower surface, connected by a bearing, the internal threaded adjusting cylinder 312 being threaded onto a fixed screw 111, and a reduction gearbox 313 at one end of the center of its upper surface, the output shaft of the reduction gearbox 313 being connected to the internal threaded adjusting cylinder 312 via a sprocket and a chain; and a grinding frame 32, mounted above the grinding seat 31, with grinding holes 321 on both sides of its surface, a grinding motor 322 mounted at the lower end of its side surface, a large pulley 323 mounted on the rotating end of the grinding motor 322, and the rotating end of the grinding motor 322 being connected to the input shaft of the reduction gearbox 313.

[0049] In this embodiment of the utility model, the setting of the support pulley 311 allows the grinding seat 31 to slide stably on the base 1. The internal threaded sleeve 312 is threaded onto the fixing screw 111, which can position the grinding seat 31 on the one hand, and the rotation of the internal threaded sleeve 312 can make it move laterally, thereby performing mobile grinding work on the rotating shaft and improving grinding efficiency.

[0050] In this embodiment of the invention, the grinding motor 322 drives the large pulley 323 to rotate, which in turn drives the first grinding belt 35 and the second grinding belt 38 to rotate. The rotation of the first grinding belt 35 and the second grinding belt 38 then performs grinding work on the rotating shaft. At the same time, the reduction gearbox 313 reduces the rotation speed, causing the internal threaded sleeve 312 to rotate slowly. This allows the first grinding belt 35 and the second grinding belt 38 to move slowly on the rotating shaft during the grinding process, thus enabling the device to automatically grind the rotating shaft.

[0051] Grinding rollers 33 are located inside the grinding frame 32 on one side, and on one side of the grinding hole 321. There are four of them, vertically distributed, and symmetrically arranged along the center line of the grinding hole 321. Adjusting rollers 34 are located inside the grinding frame 32 on the other side, and on the other side of the grinding hole 321. An adjusting baffle 341 is installed on the adjusting baffle 341, and an adjusting screw 342 is installed on the adjusting baffle 341. The adjusting screw 342 is threadedly connected to the grinding frame 32, and an adjustment screw is installed at one end of the adjusting screw 342. Tightening handle 343; Grinding belt 35, fitted onto grinding roller 33 and adjusting roller 34; Grinding roller 36, located on the other side inside the grinding frame 32, symmetrically arranged with grinding roller 33; Adjusting roller 37, located on one side inside the grinding frame 32, symmetrically arranged with adjusting roller 34, also equipped with adjusting baffle 341, tightening screw 342 and tightening handle 343; Grinding belt 38, fitted onto grinding roller 36 and adjusting roller 37.

[0052] In this embodiment of the invention, the setting of the first grinding roller 33 and the first adjusting roller 34 allows the first grinding belt 35 to be fitted onto it, forming an arc shape at the grinding hole 321, thereby enabling it to be fitted onto the rotating shaft for grinding. The setting of the second grinding roller 36 and the second adjusting roller 37 allows the second grinding belt 38 to be fitted onto it, forming an arc shape at the grinding hole 321, thereby enabling it to be fitted onto the rotating shaft for grinding.

[0053] In this embodiment of the invention, by utilizing the symmetrical distribution of the first grinding belt 35 and the second grinding belt 38, and by fitting them onto the rotating shaft, the total length of their contact with the rotating shaft can be greater than the circumference of the rotating shaft, thereby ensuring sufficient grinding of the rotating shaft.

[0054] In this embodiment of the utility model, by adjusting the tensioning handle 343 and the tensioning screw 342, the adjusting baffle 341 can drive the adjusting roller 34 and the adjusting roller 37 to adjust their positions, thereby controlling the tension of the grinding belt 35 and the grinding belt 38, so that it can meet the grinding of shafts of different sizes and improve the application range of the device.

[0055] In this invention, the grinding hole 321 and the clamping centers of the two clamping claws 212 are on the same straight line; this reduces the eccentric force on the rotating shaft during grinding and ensures uniform grinding of the rotating shaft.

[0056] In this invention, a pulley 331 is provided at one end of the bottommost grinding roller 33 and grinding roller 36. A transmission belt 332 is fitted onto the pulley 331 and the large pulley 323. When the grinding motor 322 is working, it can drive the pulley 331 to rotate, thereby enabling the bottommost grinding roller 33 and grinding roller 36 to rotate, and causing the grinding belt 35 and grinding belt 38 to rotate, thus performing efficient grinding work on the rotating shaft.

[0057] In this invention, the first grinding belt 35 and the second grinding belt 38 are arranged in an arc shape at the grinding hole 321 and are fitted onto the rotating shaft; this makes it convenient for the first grinding belt 35 and the second grinding belt 38 to be fitted onto the rotating shaft and for the first grinding belt 35 and the second grinding belt 38 to be tightened, thereby grinding the rotating shaft.

[0058] In this invention, the first grinding roller 33 and the second grinding roller 36 are staggered within the grinding frame 32, so that the first grinding belt 35 and the second grinding belt 38 are staggered; this avoids collisions between the rotation trajectories of the first grinding belt 35 and the second grinding belt 38, ensuring the normal operation of the device.

[0059] In this invention, the included angle of the clamping claw 212 is 150°; the clamping range of the clamping claw 212 is increased so that it can meet the actual requirements of rotating shaft clamping.

[0060] When using this utility model, if the worker needs to grind the rotating shaft, the worker inserts the fixed end of the rotating shaft into the square clamping frame 21 and inserts it between the two clamping claws 212. Then, the worker rotates the adjusting handle 221 to make the adjusting screw 22 rotate, and through the transmission of the sprocket and chain, the linkage shaft 23 drives the other adjusting screw 22 to rotate, thereby making the two clamping claws 212 approach the rotating shaft at the same time, and using the clamping pad 213 to clamp the rotating shaft.

[0061] Then, the grinding motor 322 is controlled to work. At this time, since the rotating shaft is not inserted into the grinding hole 321, the grinding belt 35 and the grinding belt 38 are in a relaxed state. Therefore, when the grinding motor 322 rotates, the grinding roller 33 and the grinding roller 36 at the bottom will not drive the grinding belt 35 and the grinding belt 38 to rotate. Thus, the grinding motor 322 is decelerated by the reduction gearbox 313 and driven by the chain and sprocket transmission to rotate the internal thread adjusting cylinder 312. The grinding seat 31 moves slowly on the base 1 through the sliding of the support pulley 311 and the rotation of the internal thread sleeve 312 on the fixed screw 111.

[0062] When the grinding end of the rotating shaft is inserted into the grinding hole, the grinding motor 322 stops working. Then, the operator manually puts the first grinding belt 35 and the second grinding belt 38 onto the rotating shaft. By manually turning the tightening handle 343, the rotation of the tightening screw 342 drives the adjusting baffle 341 to move. The movement of the first adjusting roller 34 and the second adjusting roller 37 tightens the first grinding belt 35 and the second grinding belt 38 respectively, so that the first grinding belt 35 and the second grinding belt 38 are in full contact with the rotating shaft.

[0063] Then, the grinding motor 322 can be controlled to work again. The grinding motor 322 uses the transmission of the large pulley 323, pulley 331 and transmission belt 332 to drive the bottom grinding roller 33 and grinding roller 36 to rotate, which in turn drives the grinding belt 35 and grinding belt 38 to rotate. Thus, the grinding belt 35 and grinding belt 38 are in contact with the rotating shaft to fully grind the rotating shaft. At the same time, the grinding motor 322 drives the internal thread adjusting cylinder 312 to rotate slowly, so that the grinding belt 35 and grinding belt 38 move on the rotating shaft while grinding the rotating shaft, thus grinding the rotating shaft while moving.

[0064] After the shaft is polished, the operator will rotate the tensioning handle 343 in the opposite direction to loosen the polishing belt 35 and polishing belt 38. Then, the polishing motor 322 can be controlled to work in the opposite direction, so that the polishing seat 31 moves away from the square clamping frame 21. At this time, since the polishing belt 35 and polishing belt 38 are in a loose state, they will not rotate with the operation of the polishing motor 322. After the device is reset, the operator can remove the shaft from the device.
